A priority search queue efficiently supports the operations of both a search tree and a priority queue. A Binding is a product of a key and a priority. Bindings can be inserted, deleted, modified and queried in logarithmic time, and the binding with the least priority can be retrieved in constant time. A queue can be built from a list of bindings, sorted by keys, in linear time.
